目的探讨子宫内膜间质肉瘤(endometrial stromal sarcoma,ESS)的超声声像图特征,提高ESS超声诊断率。方法回顾性分析经手术组织病理证实7例ESS患者的超声声像资料。结果 5例超声表现为边界清晰的肿块,内部呈均匀或不均匀低回声;1例表现为子宫后壁巨大肿块,边界欠清,内见不规则液性暗区及强光团;1例表现为宫壁内边界清晰的低回声结节,内可见多个蜂窝状小液性暗区。5例肿块内见丰富树枝状彩色血流信号,2例病灶周边环绕血流,内部血流呈放射状分布,阻力指数0.33～0.67。结论对位于子宫肌层、宫腔和/或宫颈管内的肿物,如超声表现为边界清晰或边界不清晰的低回声团块,内部回声均匀或杂乱,伴丰富低阻血流,应考虑ESS可能。
Objective To investigate the ultrasonographic features of endometrial stromal sarcoma (ESS) and to improve the diagnostic rate of ESS. Methods The echocardiographic data of 7 ESS patients confirmed by surgery and histopathology were retrospectively analyzed. Results Five cases showed a clear border of the tumor with a homogeneous or non-uniform hypoechoic inside. One case showed a huge mass in the posterior wall of the uterus, the border was not clear, A clear hypoechoic nodule within the uterine wall, showing multiple honeycomb-shaped fluid-like dark areas. In 5 cases, abundant dendritic color flow signals were seen in the lumps. The peripheral blood flow around the two lesions showed a radial distribution with a resistance index of 0.33-0.67. Conclusion For masses located in the myometrium, uterine cavity and / or endocervical canal, such as low-echo mass with clear boundary or unclear boundary in ultrasound, the internal echo is even or disorderly with abundant low resistance blood flow. ESS should be considered may.
